Title: Resin molding method for electronic parts
Inventor: TARUI MASASHI
IPC: B29C45/02
Filed: 1982-02-15
Abstract: PURPOSE:To perform a highly reliable resin sealing by a method wherein resin tablets are placed in the pot part of a sealing mold in such a manner that those tablets having a shorter spiral flow (the flowing state of resin material) are positioned on the lower side and those tablets having a longer spiral flow are positioned on the upper side, and heat and pressure are applied to them. CONSTITUTION:A lead frame is pinched between the upper and the lower molding molds 9 and 18, a plurality of resin tablets having different flowing states are placed in pots 10 and 19 as prescribed, a plunger is inserted into a hole 19, and heat 7 and 16 and pressure are applied to them. As the resin material on the lower side has a shorter spiral flow, it does not flow as far as to a runner 11b which is located apart, it flows mainly to the runners 11a and 11b, the resin material on the upper side flows to a runner 11c located apart, and it is accurately injected to the cavity which is interconnected to the runner 11b. As a result, the generation of voids can be prevented completely and the disconnection of thin metal wires can also be prevented, because it is unnecessary to increase the injection pressure above that which is required. The cross-sectional area of the runners 11a-11c is selected as phi0>phi1>phi2 respectively.

Title: Charge and discharge clamping circuit
Inventor: OOTA TAKAHIRO
IPC: G05F3/22
Filed: 1984-02-08
Abstract: PURPOSE:To vary the low level and high level of the charging voltage of a capacitor by providing a current source for setting the low-level side charging voltage and a current source for setting the high-level side discharging voltage. CONSTITUTION:When a switch SW is closed, a current flows to neither the transistor (TR) Q1 nor Q2 of a current mirror 1 and the capacitor C is charged with a constant current from the 2nd constant current source I2. The maximum voltage is the sum of the voltage drop across the resistance R1 of the 1st charging voltage setting circuit 3 and the base-emitter voltage of the 3rd TRQ3, and the capacity is not charged above said voltage. When the switch SW is opened, the current mirror circuit 1 operates and the capacitor C is discharged; its minimum value is clamped to the value obtained by subtracting the base-emitter voltage of a TRQ4 from the terminal voltage across the resistance R2 of the 2nd charging voltage level setting circuit 4.

IPC: H03H11/04
Filed: 1982-02-15
Abstract: PURPOSE:To decrease the number of elements such as resistances and capacitors and to simplify the assembly and adjustment, by having a cascade connection of same constant circuits to form a band elimination filter. CONSTITUTION:The transmission function K(lambda) of a reference LPF is set at H/(lambda<2>+alambda+b), where lambda=jomega and omega is angle frequency. At the same time, the transmission function K'(lambda) of a circuit 6 is set at H/(lambda+a/2)<2> with the feedback quantity beta set at (b-a<2>/4)H respectively. Thus the full transmission function V2/V1 covering from a terminal T1 through T2 is shown by an equation (1) and equal to the function K(lambda). Then the low and high range cut-off frequencies of a band elimination filter are set at f- and f+, K'=f-/f+, A=1-K' respectively. Then lambda=AP/(P<2>+K') is substituted for lambda of (lambda), and the function to be obtained for the band elimination filter is set at T'(P). Thus an equation (2) is satisfied. As a result, the function T'(P) is obtained from a double step cascade connection of a circuit 7 having a transmission function T(P).

IPC: G21C5/00
Filed: 1989-02-03
Abstract: PURPOSE:To perform effective spectrum operation by having a larger pressure drop coefficient of a lower resistance of a fuel assembly having duplex tube rods than that having single tube water rods. CONSTITUTION:An inlet orifice 21 is provided at a coolant passage of a fuel support metal fitting 22, the pressure drop resistance of the orifice 21 is three- four times larger than that of a lower tie plate 6, and the bore diameter of the inlet orifice 21 is changed to determine arbitrarily. In the case where a fuel assembly 9a having single tube water rods is replaced with a fuel assembly 9b having spectrum shaft rods, at the same time the orifice 21 set on the fitting 22 is replaced with the other orifice of the bore diameter whose pressure drop is lessened for an increased pressure drop at the tie plate 6. Since the flow at the position of the tie plate 6 and the orifice 21 is a liquid single phase, there is no adverse influence for the stability of a reactor core and a channel even if a distribution ratio of the pressure drop changes when the sum of the pressure drops of the plate 6 and the orifice 21 is equal.
